Remember me for one month. Building codes establish minimum requirements necessary to protect the public. Minus – tolerance decreases the amount or dimension to which it applies, or lowers a level alignment. These mandatory requirements should designate the specific qualities, procedures, materials, and performance criteria for which alternatives are permitted or for which provisions were not made in the Standard Specification.
Flatness – The degree to which a surface approximates a plane. The tolerances in this Specification do not apply to special structures or procedures not cited in the document such as nuclear reactors and containment vessels, bins and silos, circular prestressed concrete tank structures and shotcrete.
